The formula to find the midpoint of the line segment from A(x₁,y₁) to B(x₂,y₂) is:
[tex]\text{Midpoint }=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]In this case, we have:
[tex]\begin{gathered} A\mleft(5,3\mright) \\ B\mleft(3,-5\mright) \\ \text{Midpoint }=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ \text{Midpoint }=(\frac{5+3}{2},\frac{3-5}{2}) \\ \text{Midpoint }=(\frac{8}{2},\frac{-2}{2}) \\ \text{Midpoint }=(4,-1) \end{gathered}[/tex]Therefore, the midpoint of the line segment connecting A and B is (4,-1).
